## What it is
An Android library that adds sticky suspension group headers and a side index bar to RecyclerView lists, mimicking Meituan city selection, WeChat contacts, and Ele.me ordering lists. It is built on RecyclerView's ItemDecoration API rather than extra layout nesting.

## Use cases
- build a city picker like Meituan with A-Z index navigation
- create a contacts list like WeChat with sticky section headers
- implement grouped food ordering lists like Ele.me
- add a fast-scrolling alphabet index bar to any RecyclerView list
- show hovering group titles while scrolling a categorized list

## When to choose
- you need sticky section headers plus a side index bar on Android RecyclerViews
- you want an ItemDecoration-based solution without extra layout hierarchy or overdraw
- you need header views that are excluded from indexing

## When to avoid
- your project is not Android/Java based
- you need an actively maintained library with recent releases and a clear license
- you use ListView instead of RecyclerView

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, mobile-framework
- domain: mobile-development, android-tools, frontend
- platform: jvm
- tags: android, recyclerview, itemdecoration, index-bar, sticky-headers, contact-list, city-picker
